Patent DE-4120114-A1 (DE)
Title: Cleaning filters for polymer melt - by extracting e.g. set vol. from already filtered main melt stream and applying it at suitable pressure
Inventor: SIEBERT MARTIN DIPL ING
IPC: B29C48/38
Filed: 1991-06-15
Abstract: Filters for polymer melts are cleaned in an efficient manner, where the filter is washed and cleaned with already filtered melt which has been taken from the main melt stream. The melt concerned is taken according to vol. and is controlled by time for use in cleaning one filter unit or the whole filter. The extracted quantity of melt for cleaning the filter can be specific vol. used at e.g. constant high pressure. It is taken in practice by a gear pump or by the stroke of a piston. A pump removes the quantity directly to the filter. One alternative is to accumulate a specific vol. and then apply it for the cleaning operation. Its pressure is best set to suit the cleaning operation. ADVANTAGE - The method functions regardless of the overall operation of the system. Its control is simple. It is highly efficient even when operating conditions vary considerably e.g. as when recycling polymers. The system has a long service life and minimal down times.

Title: Wiper blade having at least one wiper lip
Inventor: BAIER HORST
IPC: B60S1/38
Filed: 1993-05-28
Abstract: A wiper blade of the prior art has two wiper lips which between them form a space which is connected to the surroundings by means of openings in the rubber body of the wiper blade.
